I am a developer for about 10 years now and quite new to the crypto world. I understand the basic concepts for Blockchains and tokens and proof-of-whatever. But what I am missing is:
- After finishing the white paper, what happens next?
So Ethereum had this idea, and then what. They coded the blockchain (in which language?) and were did they place it?
Until a network works, a first instance needs to be somewhere, waiting for input.
Afterwards, where is the full chain? I've read a few projects where they say "We sync instead of downloading the whole chain to make it faster to use." Where do they sync it from? How do you speak to one or many chains?
The idea is that every member of the network downloads the chain, and then sends a transaction. Where do I send it to? I mean physically, not devloper talk like (to the nodes in the network).
What I don't get is: When do I have the chain on my phone or computer? When I create a wallet? What if I just create paper wallets. Who makes sure there are enough fully downloaded and working chains available? Miners?
